Currently, the best way to contact me is by sending me an email because my phone number is not always the same number all the time, and I may not be in a position to receive calls.

AIM, Skype is another way, but I may not be online on those services all the time. For Instant Messaging (IM) communication, I very much prefer the usage of XMPP based service like Google Talk or Jabber. So, you can also contact me through my Google Talk ID, which is the same as my email. Additionally, you can connect with me on LinkedIn, or Twitter.
